Is Growing Food Wasting Water? Stories From A Surge Of Groundwater Regulations In California, Abigail Jean Lauten-Scrivner

Graduate Student Theses, Dissertations, & Professional Papers

This long-form feature story examines how the nascence of California’s new era of groundwater regulation is playing out for the farmers, families and agencies who must adapt to a sweeping new law against the backdrop of climate change.

California became the last state in the west to adopt a statewide management plan for the invaluable natural resource when it first embarked on a path toward groundwater sustainability in 2020. Known as the Sustainable Groundwater Management Act (SGMA), the 20-year plan requires California’s most depleted groundwater basins to become sustainable by 2040.

When SGMA matured in 2020, California’s next drought began …

A Thinking Person's Guide To Immigration And Environmental Racism At The Us - Mexico Border, Emma H. Kiefer

Graduate Student Theses, Dissertations, & Professional Papers

In recent years, more attention has been paid to the immigration crisis at the US-Mexico border thanks in part to the strict immigration restrictions from the Trump administration, such as the family separation policy. Immigration remains a widely misunderstood issue and arguments against increased immigration are often laced with racist stereotypes and perceptions that find their roots in centuries of US policy, court cases, and administrative rules. Similarly, the concept of environmental racism can be difficult for the American public to understand when modern-day racism alone has become more insidious. Intersectionality, a concept coined by sociologist Kimberlé Crenshaw, asks us …

A Machine Learning Algorithm Improves Surface Freeze-Thaw Classification, Fredrick Bunt

Graduate Student Theses, Dissertations, & Professional Papers

The frozen or thawed state of the land surface is an important factor affecting a wide range of natural processes such as surface water movement, the carbon cycle, and ecosystem development. It is also important for human endeavors such as permafrost engineering and agricultural planning. This makes having an accurate record important. The Freeze-Thaw (FT) Earth System Data Record (FT-ESDR) is a global, daily product that strives to be a reliable record of the FT ground state. In its current form, the FT-ESDR uses annual regression analysis of reanalysis surface air temperatures (SAT) and brightness temperatures (Tb) at each grid …

Conserving And Sharing Freshwater In The West, Kelsea Harris-Capuano

Graduate Student Theses, Dissertations, & Professional Papers

There are infinite stories to be told about water in the West. As an essential and finite resource, countries, states, tribal nations and neighbors must figure out how to manage this shared resource, whether for ecosystem sustainability, agricultural, household, or recreational use.

The Flathead Lake Biological Station in Polson, MT is one of the oldest active biological research stations in the United States. One of its former faculty, Dr. Mark Lorang, has been working on Flathead Lake’s erosion problem for over 30 years.

Sensitivity Of Lidar Derived Fuel Cells To Fire Modeling At Laboratory Scale, Anthony Albert Marcozzi

Graduate Student Theses, Dissertations, & Professional Papers

Computational models of wildfires are an important tool for fire managers and scientists. However, fuel inputs to wildfire models can be difficult to represent with sufficient detail to be both computationally efficient and representative of observations. Recent advances in fuel mapping with airborne and terrestrial laser scanning (LIDAR) techniques present new opportunities to capture variation in fuels within a tree canopy and on a landscape. In this paper, we develop a technique for building 3D representations of vegetation from point clouds created by Terrestrial Laser Scans (TLS). Our voxel based approach can be extended to represent heterogeneous crown fuels as …

For The Love Of Language: Microrituel In The Socialization Of Language Teachers, Rebekah Morgan Skoog

Graduate Student Theses, Dissertations, & Professional Papers

Language and social interaction have been determined to be intricately linked. Over the past century, studies surrounding how to learn languages have shifted the conversation on how to teach them. With the introduction of Hymes’ (1971) Communicative Competence into pedagogical literature, learning language within social context replaced the formally grammar based, traditional methods. During the early 1960’s the American Council for the Teaching of Foreign Language led the charge on providing standards and learning objectives to shift language learning towards a more integrated and communicative approach. However, based on the research of Celce-Murcia (2007), Aguilar (2007), and Ishihara & Cohen …

The Syndemic Landscape: A New Paradigm For Montana Suicide Prevention Grounded In Agricultural Renewal, Emory Chandler Padgett

Graduate Student Theses, Dissertations, & Professional Papers

Montana has had one of the highest suicide rates in the nation for half a century, and since 2000, it has risen almost 50%. Despite suicide’s alarming persistence in the state, there has been minimal academic study of suicide or mental health specifically in Montana, so this thesis attempts to answer a few questions: Why does Montana have such a high suicide rate? Is there something culturally, historically, or socially unique about Montana that contributes to suicide? Are current prevention efforts helpful, harmful, or lacking? Could a consideration of culture and land benefit an understanding of suicide in Montana? What …

Spatial Behavior, Foraging, And Population Dynamics Of A Subarctic Ungulate, Elizabeth (Libby) Parr Williamson Ehlers

Graduate Student Theses, Dissertations, & Professional Papers

The concept of density-dependence is foundational to our understanding of the ecology and management of large herbivores. As the abundance of large herbivores increases, competition for high-quality resources increases and animals select for lower-quality foods potentially resulting in reduced vital rates that cause declines in population growth. What remains unclear is how foraging at finer scales, like the ‘bite’, translates to demography. This is difficult because it’s challenging to scale bite-level foraging to population-levels. I test the fine-scale foraging mechanisms of density dependence in a large subarctic herbivore, Barrenground caribou (Rangifer tarandus granti). The nutritional landscape for arctic herbivores is …

The Corruption Of The Pardon Power, Albert Alschuler

Public Law and Legal Theory Working Papers

This Article shows how the pardon power has been corrupted over the past forty years. It begins with a brief history of federal clemency. Throughout this history, presidents gave weight to the views of prosecutors and judges and afforded politicians considerable influence. Nevertheless, until well into the twentieth century, presidents liberally granted clemency to both prisoners and ex-offenders who, after completing their sentences, sought to erase their convictions.

In the early 1930s, as parole became a common means of releasing prisoners, the use of clemency to release prisoners declined. The abolition of parole in the 1980s, however, brought no revival …

Horizontal Collusion And Parallel Wage-Setting In Labor Markets, Johnathan Masur, Eric A. Posner

Public Law and Legal Theory Working Papers

Horizontal collusion among employers to suppress wages has received almost no attention in the academic literature, in contrast with its more familiar cousin, product market collusion. The similar economic analysis of labor and product markets might suggest that antitrust should regulate labor and product markets in the same way. But product markets and labor markets do not operate identically: people behave differently as employees and as consumers. Unlike consumers who can switch products relatively easily, employees face significant frictions in changing jobs. Other labor market frictions are created by the pay equity norm and downward nominal wage rigidity. These factors …

The Folk Theory Of Well-Being, John Bronsteen, Brian Leiter, Jonathan Masur, Kevin Tobia

Public Law and Legal Theory Working Papers

What constitutes a “good” life—not necessarily a morally good life, but a life that is good for the person who lived it (sometimes called “prudential goodness” or “well-being” or “welfare”)? On some views, of course, a life cannot be good for the person who lived it if it was not also morally good, but we want to prescind from that question. Even scholars holding those views—such as some of the ancient Greeks or Kant, who arguably thought moral goodness was central to welfare—also recognized that a good life must have other features or attributes.

What might those attributes be, and …

What We Ask Of Law, Aziz Z. Huq

Public Law and Legal Theory Working Papers

A minimal, reasonably uncontroversial, demand of a legal system is that it should stabilize a polity against the chance hazards of ordinary violence and soften the blows of extraordinary, destabilizing misfortune. Law in the contemporary United States, however, has not abated the lethal toll of violent crime, the serial mass shootings of children, the endless flow of racialized police violence, or even the toll of insurrectionary violence that shadows democratic politics. The gap between law’s operation in practice and its ultimate aspirations toward social order offers a hint that something in our dominant working model of law, and its relation …

How The Senior Community Service Employment Program Influences Participant Well-Being: A Participatory Research Approach With Program Recommendations, Cal J. Halvorsen, Kelsey Werner, Elizabeth Mccolloch, Olga Yulikova

Harvey A. Friedman Center for Aging

The federal Senior Community Service Employment Program (SCSEP) provides on-the-job training to people 55 years and older with incomes at or below 125% of the federal poverty level with multiple barriers to employment. This study examined the processes by which SCSEP may influence participant financial, physical, and mental well-being. We engaged 15 SCSEP participants and case managers over four virtual and one telephone session using a participatory research method called community-based system dynamics. Activities included identifying key problem trends, variable elicitation, developing a causal map, and identifying changes to the system to increase participant well-being. Respondents identified how individual, organizational, …

Restorative Practices In Education: A Case Study, Emily Morris

Cal Poly Humboldt theses and projects

Literature shows that restorative justice practices, over time, are an effective practice for reducing negative student behaviors. This study will examine teacher and staff viewpoints on restorative practices and how they are being implemented on our campus. Additionally, this study will explore what impact restorative practices have on our campus, according to teachers and staff. My goal is to answer some of the questions that were unanswered through the literature. For instance, do the restorative justice consequences have a positive impact on student behavior? Do the staff feel that the current system, which uses restorative practices, is effective in dealing …

Comedians Are Leaders: Comedians' Use Of Humor Makes Us Feel Like We Matter, Matthew Burt

Cal Poly Humboldt theses and projects

This research examines funny functions of shared group membership – how content that clearly demarcates ingroup membership may be at the root of humor. Participants in this study listened to a recording of a stand-up comedian who was defined as being either a fellow college/university student (ingroup) or a non-college student (outgroup). Additionally, the audio either contained audience laughter or no audience laughter. Upon finishing the recordings, participants were asked to answer survey questions about their experience with the comedian, rate their overall sense of shared group identity with the comedian, their level of positive affect, distinctiveness from an outgroup, …

A Discourse Analysis On The Importance Of Outdoor Recreation For Latinx First-Generation College Students Attending California Polytechnic Humboldt, Juan Anzada

Cal Poly Humboldt theses and projects

Historically, marginalized groups, including people of color and those from low socioeconomic populations, have been at a disadvantage in accessing outdoor recreation on public lands. This project explores whether this phenomenon is mirrored in undergraduate student populations, specifically within Latinx first-generation college students. This project had a sample size of twenty undergraduate students who identified as first-generation Latinx students attending Cal Poly Humboldt. Utilizing a semi-structured interview, participants were presented with survey questions which were intended to elicit their response on how the natural environment and their participation in the environment through outdoor recreation were significant factors in their decision …

Evaluating The Use Of Barn Owl Nest Boxes For Rodent Pest Control In Winegrape Vineyards In Napa Valley, Ashley N. Hansen

Cal Poly Humboldt theses and projects

Attracting natural enemies to farms to reduce pests has long been a part of integrated pest management for insects, but knowledge of the impact of raptors on rodents and other vertebrate pests is comparatively sparse. In this study, I compared rodent prey on winegrape vineyards in Napa California with and without occupied barn owl nest boxes. We collected data before the breeding season, when hunting pressure should be light, and again when adult owls were hunting actively to feed their chicks. I used the open-hole method to quantify an index of gopher activity, and Sherman live traps to estimate the …

Cal Poly Humboldt theses and projects

PURPOSE: This study has two purposes: (a) to determine the effect of a teacher-developed physical fitness program on the performance of specific participant goals for the game of basketball and (b) to determine the impact of this same program on the overall perception of the participants amongst their peers when participating in the game of basketball. METHODS: The participants in this study included two high school males. Participant 1 had a diagnosis of attention deficit hyperactivity disorder (ADHD) and was provided services through a 504 plan. This study occurred over a 5-week period, including a 5-week intervention, with the pre …

Modulation Of Polyamines To Elucidate Function Within Osteogenesis Of Mesenchymal Stromal Cells, Amin S. Cressman

Cal Poly Humboldt theses and projects

Snyder-Robinson Syndrome (SRS), an X-linked intellectual disability that arises in children, exhibits debilitating phenotypes like severe osteoporosis. These patients demonstrate an inability to produce mineralized new bone in comparison to the rate at which bone is resorbed, thus leading to weaker skeletal structure and atraumatic fractures. The known cause of SRS is due to loss-of-function mutations within the gene that encodes Spermine Synthase (SMS). Loss of SMS enzymatic activity, which catalyzes the conversion of polyamines spermidine into spermine, demonstrates an increase in the spermidine/spermine ratio in all documented cases of this disorder. The involvement of polyamines in osteogenesis is still …

Geographic And Seasonal Variation Of Flying Squirrel Vocalizations In California, Travis A. Farwell

Cal Poly Humboldt theses and projects

Advancements in bioacoustics field studies have further elucidated spatial, temporal, and behavioral aspects of otherwise-cryptic species, as well as offering insights into species communication. The discovery of high-frequency vocalizations in North American flying squirrels in particular has allowed researchers to use ultrasonic acoustic recorders to detect these cryptic species in the wild. Investigations into vocalizations of northern flying squirrels (Glaucomys sabrinus) and southern flying squirrels (G. volans) have highlighted call type variation between species and the potential use of recorders as a tool to examine vocal activity patterns. However, high-frequency vocalizations had yet to be quantitatively …

Two male students aged 12 and 13, who had a previous diagnosis of ASD and attended a middle school in Northern California were recruited for this study. A multiple baseline across behaviors single case design was used to determine the impact of the interventions on the performance of the basketball skills. Results from this study suggest that the combined use of video …

Investigation Of Individualistic Behavior In Astyanax Mexicanus Reveals Evolutionary Divergent Patterns Among Surface And Cave Conspecifics, Jannatul Begum

Harriet L Wilkes Honors College Theses 2020 - Present

A conserved and important form of variability within and across species is behavioral individuality or the inter-individual variation in behavioral responses to similar stimuli. Although there is extensive research on the neurobiological basis of individuality, little is known about how individualistic behaviors are imposed on the brain and the mechanisms by which they change through evolution. A considerable impediment to addressing this question has been the lack of a suitable model organism with naturally occurring differences in behavior and physiology which can be manipulated experientially. Astyanax mexicanus is an emerging vertebrate model in evolutionary biology comprising two same-species morphological types. …

Novel Context Exposure Enhances Object Recognition Memory: Assessing Involvement Of Norepinephrine Neurotransmission, Eleonora Lurie

Harriet L Wilkes Honors College Theses 2020 - Present

Long-term memories are encoded within the hippocampus, but some are quickly forgotten. Brief exposure of mice to a novel context following encoding of object memory significantly enhances consolidation of the object memory. The memory-enhancing effect of post-training novelty may rely on locus coeruleus tyrosine-hydroxylase expressing neurons which co-release norepinephrine and dopamine in the hippocampus. To test the contribution of norepinephrine to this novelty effect, mice received propranolol, a synthetic beta-adrenergic receptor antagonist (10 mg/kg), to block norepinephrine or 0.9% saline as a control post-training. Pre-novel context exposure and object memory was tested 24 hr later. Results revealed that propranolol did …

Predicting Happiness On Twitter, Scott Bush

Harriet L Wilkes Honors College Theses 2020 - Present

The Hedonometer analyzes Twitter data using human evaluations of happiness to give a happiness score for a given day. The goal of this study was to be able to predict the Hedonometer’s happiness score for a given day using the Linguistic Inquiry and Word Count (LIWC). Using a sample of over 15 million Tweets gathered from Archive.org’s Twitter Stream Grab, the positive emotion dictionary of the LIWC was able to predict happiness on an independent sample, R2 = .57, p < .001. When adding seven additional LIWC dictionaries and using lasso regression, predictive power improved, R2 = .85, p < .001. This reveals that different language analysis metrics may also be able to reveal positivity and happiness within the population of Twitter.
